This application is a Continuation application of U.S. Ser. No.15/133,812, filed Apr. 20, 2016, which claims priority under 35 U.S.C. §119 to provisional application Ser. No. 62/149,777, filed Apr. 20, 2015.The contents of both applications are herein incorporated by referencein their entirety.

FIELD OF THE INVENTION

The invention relates generally to agricultural implements. Morespecifically, but not exclusively, the invention relates to improvementsof an agricultural implement that lifts and rotates to transition from afield use to a transport use.

BACKGROUND OF THE INVENTIONS

Increased tractor horsepower has resulted in larger implements capableof planting or working a much wider swath in a single pass. Transport ofthese wide implements from a storage area to a field or from one fieldto another over roads has become an important design consideration. Someearly planters required separate trailers for transport. In addition tothe cost of these special-use transport trailers, these planters arelimited in length by the practical requirements of having to load theimplement on the trailer and to unload it. The time involved with theuse of a separate trailer is increased because in loading the implementon the trailer and then in setting up the implement in the new field,the tractor must be unhitched from the implement and then hitched to thetrailer, with the reverse procedure followed at the new site. This lossof time can be significant in view of the short time typically availablewhen good planting conditions prevail, particularly when numerous fieldsmust be planted using the same implement.

Other attempts to facilitate transport of larger implements includeframes with pivoting wing sections on which row units are mounted whichmay be vertically folded. When folded, the implement is much greater inheight, frequently causing problems when attempting to pass underbridges, through gates and into storage buildings. In addition, evenwith the two outer wing sections folded, because of the increasing sizeof agricultural implements, the fixed center section may also restricttransport and storage of the implement.

Still other attempts include lifting and rotating the wings about apivot point generally in line with the tongue of the tractor. Lift androtate planters are agricultural implements with wings extendingtransversely from a tongue when the planter is in a field use. Acentralized actuator can lift the wings and attached row units duringturning, and can lift further and rotate the wings substantially in linewith the tongue for transport of the planter. This provides for anarrower implement that can be driven down most roads and that can passunder most bridges.

However, lift and rotate planters are not without problems. Due to theincreased sizes of the wings, during lifting, they may tend to want torotate or walk, with can increase the strain on the toolbar andcomponents thereof. Furthermore, when the wings increase in length toincrease the number of row units attached thereto, the amount of powerrequired by the lifting actuator, as well as the length between thepivot point and the tractor need to be increased.

Therefore, there is a need in the art for an improved agriculturalplanter that provides for an increased width to increase the number ofrow units attached thereto, while providing improved systems, apparatus,and methods for lifting and rotating the wings of the planter to allowfor turning and transition from a field use and a transportconfiguration of the planter.

It is still another object, feature, and/or advantage of the inventionto provide a lift and rotate planter that includes a telescoping tongueto allow for wings of greater length to be rotated generally in linewith the tongue while in the transport configuration.

It is a further object, feature, and/or advantage of the invention toinclude the use of multiple actuators working in tandem to lift thewings and row units of the planter.

It is still a further object, feature, and/or advantage of the inventionto include an anti-rotation link that includes substantially the sametravel as a four bar linkage used to life the wings of the planter.

It is yet a further object, feature, and/or advantage of the inventionto include fertilizer tanks positioned in saddles connected to thetelescoping tongue of the planter such that the tanks allow forclearance of the rotating wings, while also meeting the fertilizer needsof the planter.

These and/or other objects, features, and advantages of the inventionwill be apparent to those skilled in the art. The invention is not to belimited to or by these objects, features and advantages. No singleembodiment need provide each and every object, feature, or advantage.

The invention includes methods, systems, and apparatus for providingsupport of a lift and rotate style agricultural planting implement,which may also be referred to as a lift and rotate planter. The planterincludes a tongue, which includes a hitch for attaching to a towvehicle. The tongue extends generally away from the hitch. According tosome aspects of the invention, the tongue is a double sectioned,telescoping tongue, with first and second telescoping members runningside by side and combining at a wye configuration at or near the hitch.The double telescoping members allow for the length of the tongue to beextended to allow the planter toolbar to be in a transportconfiguration, and retracted to allow the planter toolbar to be in afield use configuration. Using multiple members side by side increasesthe strength and rigidity of the tongue. However, only one tongue membercan be used as well.

A frame with a lifting and rotating assembly and transport wheels ispositioned at the rear of the tongue. The lifting assembly comprises oneor more actuators and linkage systems to lift the toolbar attachedthereto in an arced manner in moving from a field use configuration to atransport configuration. The rotating mechanism can also include one ormore actuators to rotate the toolbar about a pivot member.

The linkage arms of the lifting assembly can be configured to routehoses, cables, and other components therethrough. The linkages, whichcan include upper and lower linkages, will allow the components to haveslack when needed, but also to take up at least some of the slack sothat the cables, hoses, and other components do not interfere with orget in the way during rotation and/or lifting of the toolbar.

The toolbar extends generally transverse the tongue when in a field useconfiguration, and can be rotated approximately 90° to position thetoolbar in a transport configuration. The toolbar can include wingsections, and, according to some aspects of the invention, comprises afront, upper, and rear bar in a triangular manner. An arched member canconnect the bars, and wheels can be positioned at least partially withinor under one or more of the arches and/or bars.

Row units can be attached to the front bars in push manner and/or to therear bars in a pull manner. The row units can be generally any type andcan include any type of seed meter or meters. Furthermore, hoppers canbe included to deliver seed to the meters of the row units.

To aid in prevention and/or mitigation of rotation or oscillation of thewing sections of the toolbar when in the field use configuration, suchas in a turning configuration, an anti-rotation link and system can beincluded. The anti-rotation link is a linkage arm extending generallyfrom the tool bar to a guide of the frame. An actuator is also connectedto the arm. The actuator and guide aid in the prevention and/ormitigation of the oscillation to attempt to keep the toolbar sectionsfrom rotating relative to the frame and/or tongue. Furthermore, when thetoolbar is lifted, the anti-rotation linkage arm has a geometry that isthe same as the lift linkage arms such that it will follow generally thesame arced path of the linkage arms. This is advantageous to thelifting, anti-rotation, and general function of the planter when betweenfield and transport configurations such that the anti-rotation link willnot interfere with other components and will always be repositioned inthe guide to aid in the anti-rotation of the toolbar.

Furthermore, the invention includes support tanks that are attachable tothe telescoping tongue members to house one or more tanks, such asfertilizer tanks. The tank supports can be attached in a saddle-likemanner, where they extend generally out from the side of the tonguemembers. They are configured to dip slightly downward to keep the heightof the tanks in the supports at a minimum, and below the thresholdneeded for clearance for the toolbar and attached components whenrotating to the transport configuration.

Various embodiments of the invention will be described in detail withreference to the drawings, wherein like reference numerals representlike parts throughout the several views. Reference to variousembodiments does not limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention is directed towards an agricultural planting implement,which may also be known as a planter. The planter is of the type whichincludes a field use configuration, a turning configuration, and atransport configuration. For example, when in the field use and turningconfigurations, the planter 10 will include a tongue member extendingfrom a tow vehicle, such as a tractor, with a toolbar with row unitsthat is generally transverse to the tongue. The same generalconfiguration will appear when the planter is in a turningconfiguration, with the exception that the row units will be at leastpartially lifted off the ground to allow for the planter 10 to be turnedwithin a field with reduced resistance. However, to transition theplanter 10 to a transport configuration, the toolbar and row unitsattached thereto will be lifted above the ground and to a height wherethe components of the toolbar are at least partially above the tongue.Next, a rotating mechanism will rotate the toolbar approximately 90degrees to at least partially align the toolbar with the tongue.Therefore, the planter of the invention may be known as a lift androtate planter wherein the toolbar with row units are lifted and rotatedto transition from a field use configuration to a transportconfiguration. In opposite, to transition back to the field useconfiguration, the toolbar is rotated the opposite way approximately 90degrees and then lowered after clearing the tongue to allow the rowunits attached to the toolbar to engage the ground.

Furthermore, as will be understood, the planter 10 of the inventionincludes a substantially longer toolbar than is presently known. Thisallows for more row units to be included with the toolbar of theplanter, which allows for fewer paths to be taken during planting of afield. Therefore, in order to allow for the length of the toolbar toclear the tongue and to be aligned thereto when in the transportconfiguration, the tongue will be of the telescoping type. The tongueincludes components that can telescope inwards and outwards to extend orretract the length of the tongue relative to a position of the towvehicle, which will allow the length of the toolbar to come to a restgenerally above said tongue, while not interfering with the tow vehicle.

As is known, the rotation of the toolbar to align it with the tongue ina transport configuration will provide numerous advantages. For example,the transport configuration will allow for the planter to be muchnarrower such that it can travel along roads without causing too manyproblems. Furthermore, having the toolbar positioned generally directlyabove the tongue in the transport configuration will keep the height ofthe planter at a minimum, such that it can pass under most ridges duringtransport.

Therefore, FIGS. 1-4 disclose a planter 10 according to aspects of theinvention. The planter 10 as shown in FIGS. 1-4 is in a generally fielduse or turning configuration. The planter 10 includes a telescopingtongue 12 having a first end 14 and an opposite second end 15. Asmentioned, the tongue is telescoping to allow for the length of thetongue to be varied depending on the use or configuration of the planter10. The telescoping of the tongue may be shown best in FIGS. 33-40. Thetongue, as is shown in the Figures, may include dual portions, which maybe also known as first portion 16 and second portion 17. The portionsare separate beginning at the second end 15 of the tongue 12. Thetongues converse generally at the first end 14 in a wye configuration tocombine at or near the hitch 18. The hitch 18 may be any type of hitchfor attaching the planter 10 to a tow vehicle, such as a tractor, truck,or other vehicle. The use of first and second telescoping tongue member16, 17 allows for the tongue to be more sturdy and/or strong to bothpull and support a toolbar 30 such as is included in the figures.However, it should be appreciated that not all embodiments of theinvention require the use of first and second telescoping tonguemembers, and instead, a single telescoping tongue member may be utilizedas part of the invention. For example, a wye configuration may extendfrom the frame 20 of the planter 10 at the second end 15 and extend thelength of the tongue member 12 to the first end 14 and exterminating atthe hitch 18. Such a telescoping tongue will still allow for the lengthof the distance between the hitch 18 and the second end 15 of the tongueto be varied according to need.

As is shown throughout the figures, the first and second tongue member16, 17 include an outer member 19 and an inner member 21. When first andsecond tongue members are utilized, it should be appreciated that themembers may be generally identical and/or mirror images of one another.Therefore, as is shown in FIG. 33, the tongue is in its retractedposition such that substantially all or most of the inner section 21 ispositioned within the outer section 19 of the tongue member 16, 17. Thisis also shown in FIGS. 1-4, which include all or most of the componentsof a planting implement 10. The tongue may be in the retracted positionwhen the planter 10 is in the field use and/or turning configuration. Asshown in FIG. 1, the field use configuration of the planter 10 is suchthat the toolbar 30 is generally transverse the longitudinal directionof the tongue 12. Therefore, to reduce the distance between the hitch 18and the toolbar 30, which will aid in controlling the pulling of theplanter 10, including turning thereof, the tongue 12 will be in aretracted position. This is further shown in FIGS. 33 through 36.

However, when the planter is to be transitioned from the field useconfiguration to a transport configuration, the length of the sectionsof the toolbar 30 will be such that simply lifting and rotating thetoolbar would cause a portion of the toolbar to contact the tow vehicle,as the distance between the tow vehicle and the second end 15 of thetongue 12 would not be sufficient for such rotation. Therefore, thetongue 12 is a telescoping tongue such that the length of said tonguecan be lengthened. This is shown best in FIGS. 37-40. As can be seen inthe figures, the tongue 12 has been extended such that a greater portionamount of the inner section 21 of the tongue portion 16, 17 is outsideof the outer section 19. This increases the distance between the hitch18 and the second section or end 15 of the tongue 12.

To aid in extending and retracting the inner section 21 relative to theouter section 19 of the tongue sections 16, 17, a mechanism may beincluded as is shown on an upper portion of the tongue near the firstend 14. The mechanism may include hydraulics, electronics, pneumatics,or the like, to move the inner section 21 relative to the outer sections19 of the tongue members 16, 17. This will aid in increasing anddecreasing the length of the tongue 12. It should be appreciated thatgenerally any mechanism may be used to extend or retract the length ofthe tongue sections, including those which are known in the art.

Furthermore, while a telescoping tongue has been shown and described, itis to be appreciated that when the length of the tongue is sufficient inrelation to the length of at least one-half of the toolbar 30, thetongue need not be telescoping. For example, if the width of the toolbar30 is such that a simple lifting and rotation thereof would not includeinterference between the tool bar and the tow vehicle, the tongue neednot be extended or retracted, and a set length of tongue may beutilized. Therefore, it is to be appreciated that the present inventionneed not include a telescoping tongue in all embodiments thereof.Referring back to FIGS. 1-4, at the second end 15 of the tongue is aframe section 20. The frame section 20 is a rigid member and includessuch components as transport wheels 22 connected thereto, as well as atoolbar lifting assembly 40 and a rotating mechanism 53. The transportwheels 22 are wheels that can maintain contact with the ground in mostsituations and/or configurations. As can be seen in the figures, such asin FIGS. 5-8, when the planter 10 is in a transport configuration, thetransport wheels 22 will be the support of the planter 10 opposite thehitch 18 of the planter 10, such that the wheels 22 are what support theweight of the planter 10 during transport thereof.

Also connected to the frame 20 and extending generally transversethereto in FIGS. 1-4 is a toolbar 30. The toolbar 30, as is shown in thefigures, includes multiple components. For example, the toolbar 30includes a front or first bar 31, an upper or second bar 32, a rear orthird bar 33, as well as an arched portion 34 extending generallybetween the front and rear portions and the upper portion. The toolbar30 is not to be limited to the exact configuration shown in the figures,however, and is to be generally known as a toolbar for supporting suchelements such as row units, markers, additional ground support tires,and the like. For example, as is shown in FIGS. 1-4, the planter 10includes a plurality of row units 36. These row units 36 include aplurality of pulling or rear units 37 which are operatively attached tothe rear bar 33 of the toolbar 30. Such row units may be attached in anyway, such as by the use of four bar linkages, as is shown and describedin U.S. application Ser. No. 13/829,726, which is hereby incorporated byreference in its entirety. Likewise, the planter 10 may include aplurality of push or front row units 38, which are shown to be connectedto the front bar 31 of the toolbar 30. Therefore, the planter 10 as isshown in the figures may be a push/pull type planter in which there areboth push row units 38 and pull row units 37. The inclusion of push andpull row units allows for a greater number of row units to be attachedto the toolbar 30 such that more seeds can be planted in a single pathwith the planter 10. However, the invention should not be limited tosuch a configuration, in the use of only push and/or only pull row unitsis intended to be included as part of the invention.

Furthermore, the middle or upper bar 32 of the toolbar 30 is shown to beraised above the front and rear bars 31, 33. This is connected by one ormore arch-type members 34, as is shown in the figures. The inclusion ofthe upper bar 32 and arch members 34 allows for the re-positioning ofthe transport wheels 39 of the planter 10. The transport wheels 39 areoperatively connected to the toolbar 30 to allow for the wheels tocontact the ground when in a field use configuration, such as that shownin FIGS. 1-5. Positioning the wheels between the front and rear rowunits 38, 37 allows for greater stability of the planter 10, during thefield use configuration of the planer 10. However, to provide greaterrigidity and stability for the construction of the toolbar 30, theinclusion of the middle bar 32 above the wheels and connected by thearch 34 still provides clearance for the wheels 39 relative to thetoolbar 30.

Furthermore, as is shown in FIGS. 41 and 42, the wheels 39 can beconnected to the toolbar 30 via a linkage 81 that also includes anactuator 80 operatively connected between the linkage 81 and an archportion 34 of the toolbar 30. The actuator 80, as will be understood,allows for the toolbar 30, and thus row units 36 to be at leastpartially lifted off the ground, such as when in a field turnconfiguration. For example, as is shown in FIG. 42, the linkage 81 isconnected at a point 82 coinciding with the axle of the wheel 39. Thelinkage 81 extends to have a connection point 83 connecting to a rod ofthe actuator 80. There is also a connection point 84 of the linkage 81which connects to the rear bar 33 of the toolbar 30. Extending the rodof the actuator 80 will cause the wheel 39 be pushed towards the ground.However, pushing the wheel 39 towards the ground will compact the groundto a point wherein the movement of the actuator 80 will be in an upwardsmanner, such as that shown by the arrow 87 in FIG. 42. This is due tothe connection of the connection point 83 and connection point 84 of thelinkage 81. Continuing to extend the actuator 80 will cause thecomponents of the toolbar 30, including the first bar 31, second bar 32,third bar 33, and arch 34 upwards in the direction of the arrow 87. Asthe row units 36 are connected to the components of the row unit 36,they will be raised off the ground as well. However, the raising of therow units 36 need only be enough to lift the portions of the row unit 36out of engagement with the ground. While the row units 36 are not inengagement with the ground, it will be easier for the planter 10 to beturned via the tow vehicle, as substantially the only portions of theplanter 10 in contact with the ground will be the ground support tires39 and transport wheels 22. Once the turning of the planter 10 has beencompleted, the rod of the actuator 80 can be retracted into the housingsuch that the toolbar 30 and attached row units 36 will be lowered backinto contact and engagement with the ground for further planting.

Referring back to FIGS. 1-4, still additional components of the planter10 include markers 35 extending from ends of the toolbar 30. The markers35, as is known, can be used to aid in determining where the edge orboundary for planting is.

Additionally, the figures show the inclusion of central hoppers 29 forholding one or more varieties, hybrids, or types of seed to be plantedby the row units 36. For example, the row units 36 of the planter 10 maybe of any type. For example, the row units and/or seed meters associatedtherewith may be of the type that are described in U.S. application Ser.Nos. 13/829,726, 14/478,222, 14/619,758, and/or 14/592,965, which areall hereby incorporated by reference in their entirety. This includeselectrically driven seed meters, hydraulically driven seed meters,multi-hybrid type seed meters, and the like. However, it is to beappreciated that these are not the only types of seed meters, row units,seed delivery systems, and the like that are contemplated for use, andit is to be appreciated that generally any type, style, and/orconfiguration of seed meter, row unit, linkage connection, seed deliverysystem, down force, and the like can be used and included in the planter10 of the invention.

Furthermore, while not explicitly shown, the planter 10 may include theuse of an air seed delivery system, which is shown and described in U.S.application Ser. No. 12/829,654, which is also hereby incorporated byreference in its entirety. Therefore, it is to be appreciated that anytype of planting system, including hoppers, row units, seed meters, seeddelivery systems, and the like may be included and used with the planter10 according to aspects of the invention.

The planter 10 in the field use configuration is also shown in FIGS.9-12 and 17-19. FIGS. 9-12 and 17-19 show elements of the planter 10without all of the elements shown in FIGS. 1-4. For example, the rowunits 36 have been removed. In addition, the markers 35 and bulk hoppers29 has also been removed to show the tongue 12 and toolbar 30 in moredetail. For example, FIGS. 9 and 10 show the tongue in greater detail asit attaches to the frame 20 and toolbar 30.

However, additional figures included in the present disclosure show theplanter 10 after it has been transitioned from the field useconfiguration to the transport configuration. For example, the planter10 with all elements in the transport configuration is shown in FIGS.5-8. As is shown in FIGS. 5-8, the toolbar 30 and all componentsattached thereto have been lifted above the height of the tongue 12 androtated approximately 90 degrees, such as in the direction of the arrow48 in FIG. 10. Such rotation can be accomplished by a rotating mechanism53 wherein one or more actuators operatively positioned and attached tothe frame 20 is extended or retracted to rotate the toolbar 30 and allcomponents attached thereto in the direction of the arrow 48. Therefore,a pivoting pillar or cylinder can also be included at the frame 20 andconnected to the toolbar 30 to provide for the rotation of the toolbar30 relative to the tongue 12 and the frame 20.

To transition the planter 10 from the field use configuration to thetransport configuration as is shown in FIGS. 5-8, the toolbar 30 needsto be lifted, and, if needed, the tongue 12 needs to be telescoped toincrease the length between the hitch 18 and a second end 15 of thetongue 12. Such extension, as has been disclosed, is required when thelength of the toolbar 30 is such that there would be interferencebetween the toolbar 30 and the tow vehicle without said extension oftongue length. Therefore, the tongue 12 may be first extended, as haspreviously been shown and disclosed, such as in FIGS. 33-40. Next, orprior to the extension of the tongue 12, the toolbar 30 can be lifted.

To lift said toolbar 30, the invention includes a toolbar liftingassembly 40 operatively positioned and attached to the frame 20 at thesecond end 15 of the tongue 12. The toolbar lifting assembly 40includes, among other components, one or more lifting actuatorsconnected via a linkage to the toolbar 30. For example, as is shown inthe figures, the toolbar lifting assembly 40 includes a first actuator41 and a second actuator 42. Each of the actuators 41, 42 include acylinder or housing 44 and a rod 46 for extending and retracting via orrelative to the housing 44. In the figures of the disclosure, extensionof the actuators 41, 42 will lift the toolbar 30 and components attachedthereto relative to the frame 20. While first and second actuators 41,42 are shown to be included as part of the lifting assembly 40, itshould be appreciated that the invention need not require two specificactuators. For example, a single actuator capable of lifting the toolbar30 and components attached thereto is contemplated to be used as part ofthe lifting assembly 40. Furthermore, a number greater than twoactuators can also be utilized to lift the toolbar 30 and attachmentcomponents relative to the frame 20. The size and number of actuatorscan be selected based upon a number of components. For example, thelength of the toolbar 30, the number of row units 36 attached thereto,the size and weight of the bulk hoppers 29, the type of seed beingplanted via the row units 36, as well as additional factors may dictatethe size and number of actuators as part of the lifting assembly 40.Therefore, the present invention is noted to include generally anynumber of actuators for being capable of lifting said toolbar 30 and/orattachment components.

Referring to FIGS. 25-28, the lifting assembly 40 is shown in greaterdetail. For example, the actuators 41, 42 are shown. To combine thepower of the first and second actuators 41, 42, a trunnion 54 can beoperably connected to the actuators 41, 42, such as at the housing 44 ofthe actuators 41, 42. Therefore, the trunnion 54 will cause thecylinders to act in synchronicity or unison to combining the power ofthe separate actuators to work as if there was one larger actuator. Thetrunnion 54 can be any mechanism capable of operably attaching to aportion of the actuators, and not necessarily to the actuatorsthemselves, but to components connected thereto, to combine the power ofthe actuators to be able to lift the toolbar 30 and attachmentcomponents thereto.

Furthermore, as is shown in the figures, the lifting assembly 40 caninclude a linkage assembly 50, comprising first and second upperlinkages 51 as well as first and second lower linkages 52. The upperlinkages 51, as is shown in FIG. 25, are positioned on opposite sides ofthe first and second actuators 41 and rotatably connected to a centerpost 43. The upper linkages 51 can be connected at a first end to theframe 20, such as the rotating pillar of the frame 20, and at a secondend to the toolbar 30. Likewise, the lower linkages 52 can be attachedat a first or front end to the frame 20, such as at a rotating portionthereof, and at a second end to a portion of the toolbar 30 as well.Furthermore, as is shown in FIGS. 23 and 24, portions of the upperlinkages 51 may be connected to the trunnion 54, which is operablyattached to the actuators 41, 42. This will aid in having the trunnioncombine the power of the separate actuators to lift the toolbar 30 andattach components thereto. Therefore, FIG. 26 is a side elevation viewof the planter 10 showing the toolbar 30 in the lowered field useconfiguration. However, transitioning to FIG. 20A, the actuators havebeen extended to extend the rod 46 relative to the housing 44 of thecylinders 41, 42. The actuators 41, 42 are connected to the frame 20 toallow the actuators to rotate as they extend. The path of the rotationis also aided by the upper and lower linkage arms 51, 52 on oppositesides of the actuators 41, 42. Thus, the length and shape of the linkagearms 51, 52 can provide a desired path for the lifting and rotation ofthe toolbar 30 via the extension of the actuator rods to best lift thetoolbar 30 and attached components. As is shown in FIG. 20A, the toolbar30 and attached components have been lifted such that the wheel 39 issubstantially above the tongue 12 such that rotation of the toolbar 30will have enough clearance between the components of the toolbar 30 andthe components of the tongue 12 to transition the toolbar 30 from theconfiguration shown in FIG. 1 to the configuration shown in FIG. 5. Insuch configuration shown in FIG. 5, the toolbar 30 is generally alignedwith the longitudinal axis of the tongue 12 such that the planter 10 isin the transport configuration to allow for the planter 10 to betransported from one location to another while taking up a minimal widthand height.

Therefore, once the toolbar 30 and attached components have been liftedas is shown in FIG. 28, a rotating assembly (not shown) can be activatedto rotate the toolbar 30 approximately 90 degrees, such as in thedirection shown by the arrow 48 to transition the toolbar 30 from theposition transverse to the tongue 12 to a position generally aligned orin parallel with the tongue 12. To transition the planter 10 from thetransport configuration back to the field use configuration, the entireprocess is reversed. Therefore, the rotation mechanism is activated torotate the toolbar 30 and attachment components 90 degrees in theopposite direction of the arrow 48 to configure the toolbar'slongitudinal axis generally transverse or perpendicular to thelongitudinal axis of the tongue 12. As such, a configuration, theactuators 41, 42 can then be retracted and the toolbar 30 and attachmentcomponents can travel the path dictated by the upper and lower linkagearms 51, 52 of the linkage assembly 50 to lower the toolbar 30 to thefield configuration, such as that shown in FIG. 3. As such aconfiguration, the planter 10 is in a position to begin planting seedfrom the central hoppers 29.

While the invention has been shown to be a lifted rotate mechanism withvarious actuators and linkages, it should be appreciated that, due tothe length of the toolbar 30, and thus the weight associated there with,additional safety, down pressure, and stress reduction mechanisms can beincluded to prolong the life of the planter. For example, when thetoolbar 30 and components attached thereto have been slightly lifted,such as in a turning configuration, the any turning of the planter maycause the end sections of the toolbar to want to oscillate or otherwisewalk. While the rotating cylinder of the rotating mechanism can aid inmitigating such oscillation or rotation of the ends of the toolbar 30,this cannot prevent all of said rotation. Furthermore, the continuedoscillation can create stress on the components of the rotatingmechanisms such that the failure rate may be higher than what isdesired. Therefore, the invention includes a novel and uniqueanti-rotation link system to aid in preventing or otherwise mitigatingthe oscillation, rotation, or walking of the toolbar 30, such as whenthe toolbar 30 is in a turning configuration where it is raised at leastpartially off the ground. Furthermore, it should be appreciated thatsuch an anti-rotation link system of the invention can prevent anyoscillation or walking while the toolbar and components thereof are alsoengaged in the ground, such as to provide a more straight line plantingof the row units in the ground.

FIGS. 20-24 show details of the anti-rotation link system according toaspects of the invention. The location of the anti-rotation link systemis shown to be spaced outwardly from the central frame 20 and liftingassembly 40. However, the exact placement of the anti-rotation linksystem relative to the toolbar may be varied according to the length ofthe toolbar, as well as other factors so as to prevent or mitigate theoscillation of the ends or wings of the toolbar 30. Therefore, as shownin FIGS. 20-24, the anti-rotation link systems includes an anti-rotationlink 60, which extends from a toolbar link 64 to and towards a guide orcatch of the central frame 20. The anti-rotation link 60 includes afirst free end 61, which may be a roller capable of rotating at the endof the link 60. Thus, the roller 61 allows for the guided movement ofthe link 60 relative to the guide 67, as would be understood. At anopposite end of the link 60 is a link connection point 63 connecting theanti-rotation link 60 to a toolbar link 64. The toolbar link 64 is amechanism connecting the anti-rotation link 60 to the toolbar 30, suchas at the rear bar 33 and/or the upper bar 32. Thus, the toolbar linkcan be attached to the toolbar 30 in any known manner, such as bybolting, welding, or the like. Further components of the anti-rotationlink system include an actuator 66 having one end 62 connected to theanti-rotation link 60 and an opposite end connected to the toolbar link64. The cylinder or actuator, which can be a hydraulic, pneumatic,electric, linear actuator, or some combination thereof, can aid inproviding a downforce or down pressure to keep the ends of the toolbarfrom rotating, swiveling, or walking. Therefore, the actuator 66 can beset to try to aid in maintaining the travel of the toolbar section 30.

Furthermore, the length and configuration of the toolbar link 64connected to the anti-rotation link 60 will allow for the toolbar linkto have the same path of travel to that of the four bar linkage system50, which is used to lift the toolbar 30 and components attached theretoduring transition to and from the field use configuration and transportconfigurations. Having the same travel, such as by having the samegeometry of the linkage systems, provides numerous advantages. Thisallows for the toolbar to be lifted, such as shown in FIGS. 20-22. TheFigures show the extension of the actuators 41, 42 of the lifting system40. The upper and lower linkages 51, 52 will cause the travel, which isan arched travel of the toolbar as it is lifted via the actuators. Thissame arched travel can be accomplished with the anti-rotation link 60due to the geometry of the link 60 as well as the connection to andgeometry of the toolbar link 64. Having the systems travel the same pathwill allow for the toolbar to be lifted in unison such that it willreduce the rotation, swiveling, oscillation, or the like of the toolbar30 relative to the tongue 12. Furthermore, the actuation of the cylinder66 of the anti-rotation system will further control the lifting of thetoolbar 30, such as further preventing any oscillation of the toolbar30.

The free end 61 of the anti-rotation link 60, as is shown in FIGS.20-22, is allowed to travel from within the guide 67 to outside theguide. Furthermore, the arch of travel can be shown best from FIGS.20-22, wherein the free end 61 is shown to be above and forward of theguide 67 when moving from the configuration shown in FIG. 20 to thatshown in FIG. 22. Therefore, that arch is the same as the toolbar, whichprovides for the anti-rotation link to not get caught up in aspects ofthe planter 10, which could damage the planter during lifting thereof.

Therefore, the inclusion of the anti-rotation link provides numerousadvantages both during field use configuration and in transitioning tothe transport configuration. For example, in field use configuration,such as when turning said planter 10, the anti-rotation link will reducethe stress on the rotating cylinder of the rotating mechanism, such asby reducing, preventing, or otherwise mitigating oscillation of thetoolbar 30. Having the link reside in a guide 67 and with the actuator66, this will aid in maintaining the transfers alignment of the toolbarrelative to the tongue. Still further, having the geometries of thelifting linkage system 50 and the linkage system of the anti-rotationlink 60 be similar or the same will allow for the path of travel of thetoolbar as well as the path of travel of the anti-rotation link systemto be the same during the lifting of the toolbar and components attachedthereto. This will make the transitioning easier.

Still additional components of the planter 10 are shown throughout thefigures. As the weight of the toolbar is to be minimalized so that thelifting and rotating of the toolbar can be accomplished using the leastamount of force, the positioning of fertilizer or other tanks can bemoved from their standard location at or near the central frame or at ornear the central hoppers 29 to a location as shown in the figures,connected to the first and second component 16, 17 of the telescopingtongue 12. This is shown throughout the figures, and in particular inFIGS. 1-8, 29-32, and 43-50. Therefore, as is shown in the figures, thefertilizer or other chemical tanks 28 can be positioned alongside of thetongue 12 and connected operatively thereto. To connect the tanks to thetongue, the invention includes the use of unique and novel tank supports24, 26. The tank supports 24, 26, are shown to be on opposite sides ofthe tongue 12 and connected to only one of the first or second tongueportions 16, 17. However, it should be appreciated, that when a singletongue is utilized, the one or more tank supports 24, 26 can be attachedto the single tongue member, or else the only one of the two tanksupports be attached to the tongue member.

The tongue support members, shown best in FIGS. 47-50 without theinclusion of the tanks, include a connecting member 70, which may besimilar to a saddle type connection. As is shown, the saddle connection70 is a horseshoe shaped member which can be positioned over thetelescoping portion 16 or 17. The connection member 70 can then beconnected, such as via nuts and bolts, or other connection members tosecure the support member 24 to the tongue portion. Connecting to andextending generally from the plurality of connection member 70 is thesupport body 71. The support body 71 includes generally a front portion72, side portion 73, and a rear portion 74. Furthermore, in connectingto all of the front sides and rear portions is a bottom or basinportion. The basin portion allows for the tanks to be positioned at alower position within the support body 71. Having the body or basinportion lower will allow the tanks to reside lower such that the tops ofthe tanks will be at or near the upper portions of the tongue. This willallow for the amount of clearance required by the lifting of the toolbar30 and the components attached thereto to remain unchanged, such as ifthe tanks were not included and/or attached to the tongue 12 itself.While the body 71 of the supports 24 includes a particular shape asshown in the figures, it is to be appreciated that said shape isincluded only to match one of many types of fertilizer tanks 28 as isalso shown in the figures. For example, as is shown in FIGS. 29, 43, and46, the fertilizer tanks are generally oval shaped and elongate suchthat three tanks are shown to be fitting in a single support body 71.However, if the tanks were to be rectangular, square, or any othergeometric shape, the support bodies could be varied to accommodate saidgeometric shape in such that the tanks will reside within the supportbody 71 to remain at a lower profile to allow for the clearance of thetoolbar 30 and attached components when transitioning to the transportposition. For example, as is shown in FIG. 5, the row unit 36, whichwill generally be the lower hanging portions of the toolbar 30 will needto be raised enough such that the lower portions of the row units (e.g.,furrow opening and closing wheels, seed delivery systems, etc.) areraised high enough to clear the tops of the tanks 28 and any componentsextending therefrom. As this is intended to be at a minimum, the lowerprofile of the tank support basins can be varied to accommodate thevarying shapes of the tanks. Thus, as is shown in FIG. 31, the tanks andportions extending therefrom, are still below the highest portion of thetongue member 12 such that normal clearance of the tongue will alsosatisfy the clearance of the fertilizer tanks 28 within the supportmembers 24, 26 as well.

The tank supports can comprise generally any rigid material capable ofsupport said tanks. For example, steel, plastic, or other combinationsof materials can be utilized to support the tanks. Furthermore, whilethe saddle or U-shaped connecter member 70 is shown to connecting thetank supports to the tongue, it should be appreciated that other ways ofattaching the tank supports to a tongue can be accomplished and areintended to be included as part of the invention. This includes welding,connection members, and the like. Furthermore, as has been disclosed,the tank supports need not be required in all configurations, as thefertilizer and/or other chemical tanks can be positioned elsewhererelative to the planter 10 to satisfy the requirements thereof.

Still other advantages of the components of the invention are to beappreciated. For example, the upper and lower linkage arms 51, 52 of thelifting linkage 50 are configured to be a hose routing and take upmembers as well. The hoses for the various components of the planter canbe routed such that they are routed behind and above the lower linkagearm 52 and in front of and above the upper member 51 and to theirdesired or end use location. Having them routed in such a configurationrelative to the upper and lower linkage arms allows for slack andretraction of the hoses and other cables to be utilized such that thelifting and rotating of the toolbar can be accomplished without damageto the hoses or cables of the planter 10. For example, as best shown inFIG. 25, when the toolbar 30 is in a field use configuration, the upperand lower linkage arms 51, 52 are more parallel with the ground. Thusthe distance from the back to the front is at a maximum or near maximum.In such configuration the hose and cables will be stretched such thatthey are taught or in a more taught configuration such that slack is notallowing the cables to bounce around. However, as is shown in FIG. 27,when the toolbar 30 has been lifted, the linkage arms are in a morevertical configuration. Therefore, there is less distance between theportions of the linkage arms such that the hoses can be extendedgenerally vertically about or through the linkage arms. This extensionwill be required such that the hoses are further away from theirbeginning location when lifted. In addition, when the toolbar 30 is tobe rotated, having the hoses in such a configuration with the morevertical oriented linkage arms 51, 52 will allow for the rotation of thehoses and cables as well without damaging said hoses or cables.

It is to be appreciated that many variations can be included as part ofthe invention. For example, the number of row units and the width of thetoolbar 30 can be varied. In addition, the toolbar 30 can includesections, such as wings. As is shown in FIG. 11, the toolbar 30 may besplit having an inner section near the frame 20 as well as outer wingsections 56, 57. For example, as viewed in FIG. 11, the right side wingis known as the first wing 56, while the left side wing is known as thesecond wing 57. Having a solid or rigid length of toolbar along the fulllength of said toolbar can have a negative impact on the ability ofplanting of the outer row unit 36. Therefore, aspects of the inventioninclude a break along the length of the toolbar, which is showngenerally at the wing pivot 58 between the inner section of the toolbar30 and the wing sections 56, 57. The float or pivot 58 between the outerwing sections and the inner section of the toolbar allows for the outerwings to rotate about a horizontal axis relative to the inner wingsection. Furthermore, a one or more actuators can be provided at thepivot 58 to provide for downforce or down pressure at the outer wings,such as when planting on a hillside or uneven terrain. Such a downpressure configuration is shown and described in U.S. patent applicationSer. No. 13/927,177, which is hereby incorporated by reference in itsentirety. Still additional benefits are meant to be included with theinvention.

Therefore, a lift and rotate planter has been shown and described. Thenumerous advantages of the varying elements of the planter 10 will beapparent to those skilled in the art. Furthermore, it is to beappreciated that the figures described herein are shown for exemplarypurposes, and numerous changes, variations, or the like are intended tobe included within the scope of the invention. For example, the positionof the ground support tires 39, the shape and rigidity of the toolbar30, the shape, length, and telescoping of the tongue, as well as thelifting and rotating mechanisms of the system can all be variedaccording to the size and need of the planter. However, the numerousaspects of the invention provide for numerous advantages over lift androtate planters as are currently presented.
